Abstract

The present research aims to study the way heat transfer occurs within micro and nano channels of a micro-heat exchanger. Several such heat exchangers were manufactured and a test rig was conceived and built in order to test them. For the experimental investigations, a method to test copper micro-tubes reaching 40μm in depth and 0.35 mm in width was advanced. The shape and dimensions of these micro-tubes were measured using laser profilometry. Experimental results showed different behavior for micro-heat exchangers, revealing a great importance of flow conduits configuration and the chosen path for working fluids.
